Abstract
A compensated comparator is provided, including a decision stage and a differential stage provided with two transistors connected by their sources, the differential stage being provided with compensation means to compensate the effects of a dispersion of the threshold voltages of the transistors forming the differential stage, the compensation means including first and second capacitors each connected to a gate of one of the two transistors, and being configured to memorize a voltage that is a function of a threshold voltage of the considered transistors.
